BACKGROUND Dracocephalum kotschyi Boiss. is a valuable source of rosmarinic acid (RA) and methoxylated hydroxyflavones (such as xanthomicrol cirsimaritin) with antioxidative antiplatelet effects antiproliferative potential against various cancer cells. The extensive application nanotechnology in hairy root cultures new sustainable production platform for producing these active constituents. In the present study, roots derived from 4-week-old leaves Agrobacterium rhizogenes strain ATCC15834...
Abstract This study aims to evaluate the degradation and mineralization of Malachite Green (MG) in an electro-Fenton process (EFP). We studied influence several important parameters including solution pH (2–11), current density (0–20 mA/cm 2 ), H O concentration (0–200 mg/L) MG concentrations (200, 600, 1000, 1500, 2000, 3000 at different reaction time (2.5–30 min). The intermediates produced during were determined by GC–MS. optimum pH, found be approximately 3, 10 50 mg/L, respectively. It...
Abstract BACKGROUND The genus Rosa comprises economically important horticultural plants belonging to the family Rosaceae. Recently, use of different species has increased owing their multipurpose properties (ornamental, food and medicinal uses). In this study, 21 accessions genotypes were compared for fruit phytochemical composition color parameters. RESULTS highest antioxidant activity (37.86 mg AAE g −1 FW) total phenolic (8.17 GAE FW), flavonoid (2.53 QUE carotenoid (20.21 ascorbic acid...
Flavor is one of the most important quality properties cacao beans, playing a key role in admissibility cocoa products, such as powder. This study examined industrial processes influencing flavor beans. The Ivory Coast beans were used after their alkaline treatment with potassium carbonate (up to pH 7.5-8) and being roasted at 115-120°C for 60-70 min. volatile components extracted using Likens-Nickerson simultaneous distillation-extraction (SDE) apparatus. compound profiles identified by...
ABSTRACT A new, simple, and reliable method for rapid preconcentration of trace levels malachite green from water samples is developed using a sodium dodecyl sulfate coated alumina solid phase. The effects pH, flow rate sample solution, foreign ions on the sorption have been investigated. Two micrograms 250 mL aqueous phase could be quantitatively extracted into 500 mg SDS alumina. collected molecules were eluted with 2 acetonitrile determined spectrophotometrically at 617 nm. detection...
Abstract Background: The petals of Rosa species are used in the food industry and various traditional medicinal products, but few studies exist on phytochemical composition antioxidant activity L. grown Iran. Objective: Phytochemical characteristics some phenolic compounds six were studied. Methods: Total content, total flavonoid determined using Folin–Ciocalteu reagent, aluminum chloride method, ferric-reducing power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays, respectively. An HPLC...
A new Fe^{3+} ion-selective membrane electrode based on 6-ketomethyl phenanthridine (6-KMPT) and 1-(4-dimethyl aminophenyl)-2-(5H-phenanthridine-6-ylidene)-ethanone, which were incorporated in a plasticized polyvinyl chloride (PVC) membrane, is described. The optimized demonstrated linear dynamic range of 5.2 \times 10^{-6}-1.0 10^{-2} M, with near Nernstian slope 19.5 \pm 1.5 mV per decade detection limit 1.2 10^{-6} M. showed high selectivity for ions comparison to other metal ions. effect...
The toxic air pollutants such as benzene, toluene, ethylbenzene and xylene (BTEX) well asbestos are considered hazardous because of their role in adverse impacts on human health. Accordingly, this research was conducted to evaluate the levels, seasonal variations, spatial mapping, potential sources, health risk assessment BTEX compounds fibres ambient Tehran. Air samples were collected by NIOSH1501 method at 15 different sample stations from March 2018 February 2019. Charcoal glass tube used...
Abstract Contamination of water with bacteria is one the main causes waterborne diseases. The photocatalytic method on basis bacterial inactivation seems to be a suitable disinfectant due lack by-products formation. Herein, g-C 3 N 4 /Fe O /Ag nanocomposite combined UV-light irradiation was applied for two well-known namely, E. coli and B. subtilis . prepared by hydrothermal method, subsequently it characterized XRD, FT-IR, SEM, EDX PL analyses. optimum conditions established both were as...
In this study, flowers of nine mullein species (Verbascum erianthum, V. songaricum, speciosum, szovitsianum, stachydiforme, sinuatum, haussknechtianum, cheirantifolium, and saccatum) were collected from Iran. The total flavonoid content (TFC), antioxidant activity, carotenoid (TCC), β-carotene the amount phenolic compounds determined in all species. Quantitative analysis was performed using high-performance liquid chromatography with diode-array detection (HPLC-DAD).Verbascum saccatum...
